{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This visualization shows a hierarchical tree of world countries, with nodes and text labels arranged horizontally. The text size varies with depth, creating a visual distinction between parent and child nodes. The visualization uses D3 v5’s `tree` layout, `hierarchy`, `stratify`, and `linkHorizontal` to compute and draw the graph structure, with SVG paths for links and text elements for labels. Pan and zoom interactions are enabled via `d3.zoom`. The data is loaded from a `data.json` file, though the currently active code references a `down_s` variable instead.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6d764a49434144378b169a6ea9ba355d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
